"In 1193 (1981.), I submitted my first article [...] and in 1197 (1987.), I became a member" Seems obviously wrong, or is that yet another dozenal notation, where what looks like the digit three is really a one? Because it should

by rep_lodsb 10mo ago
The dozenal movement seems based (no pun intended) mostly on opposition to the metric system. The article on page 38 is really funny to anyone not in the US: Fahrenheit temperature usually ranges from about 0° (cold) to about 100°

The "dividing things by two" argument makes a lot of sense! And if you need ⅓ and ⅕, they aren't too bad either: .5555 and .3333 repeating.

Yes, with that name it really should have an emulation mode similar to the NEC V20/V30 (although that one only did 8080, not Z80)

by rep_lodsb 10mo ago
Only the Z80 refetched the entire instruction, x86 never did it this way. Each bus transfer (read or write) takes multiple clocks: CPU Cycles per theoretical minimum per byte for block move Z80

The prevailing opinion seems to have shifted towards using the frame pointer for its special purpose, in order to improve debuggability/exception handling? But the article is really quite misinformed. As you say, many mainframe/mi

I've looked at the EXE file, and it's supposed to print "This program cannot be run in DOS mode." when run under (real or emulated) DOS. The reason why it fails to do that is that the compiler did not set the memory al

IIRC, even GW-BASIC allowed direct access to the hardware via peek/poke/inp/out. When you turned on the PC, it loaded the first 512 byte sector from floppy or hard disk into memory and transferred control to that. In theory,

Not sure if it's 100% slop, but as someone knowledgeable about older x86 processors, I can say after a casual look through "src/emulator/cpu.c" that the code is pretty terrible and often wrong. For example, "su

Yeah, it's really irresponsible how Pascal sacrifices such safety features in the name of faster and more compact code... oh, wait, the compiler stops you from calling a function with incorrect parameters? Bah, quiche eaters!

On x86, the RET instruction can add a constant to the stack pointer after popping the return address. Compared to the caller cleaning up the stack, this saves 3 bytes (and about the same number of clock cycles) for every call. There is noth
